Don't you think FS competitons are not enough? Skaters compete every year just at Worlds, Euros and GP. Every four years the Olympics. And some minor competitions such as Nebelhorn, Finlandia Trophy, Karl Schaefer. And obviously Nationals. But from march till october no competitions
But if you think about other sports, the athlests have many many many more competitions than skaters. They play the whole year. For example volley, soccer, basket, baseball...
They play every year with the NTs (in the summer and autumn) and with the clubs (in the winter and spring).
